44
Wow, the guys have already hit that question on the head.
Here's some quick guestimates.
Used 44 Mag prices.
Taurus start at $300 and go up (Lifetime Warranty) available with 5 & 6 shot cylinders.
Smith & Wesson models 29 & 629 depends on barel length and version of model. Start at $400 and go up from there.
The model 29 is the Blue & nickel version and the 629 is the Stainless model.
Tons of variations are available. Classic, Silhouette, Mountain gun, mountain gun light.... also a large range of barrel lengths up to 8 3/8.
Colt, model Anaconda. 6 shot ,4 inch through 8 inch barrel ported and Non ported
Only available in Stainless. Start at $500 used and take you to $1000 New.
Ruger Redhawk and Super Redhawk. Redhawk was the earlier design and the Super Redhawk was developed later and has a larger frame and also has built in scope mounts right on the frame. Both of these are built like Brick Sh-t houses and will last a lifetime. The Redhawk came in Blue and Stainless and the Super Redhawk to my knowledge only came in Stainless. I would think you may be lucky and find a Redhawk for around $350 and the Super Redhawk would probably start around $400 and go to $550 if it's already scoped. depending on scope choice.
The above are just some of your Double Action Revolver choices.
There's also a bunch of single action 44 mags such as the Blackhawk, Super Blackhawk, Bisley, Vaquero...
There's also a few mfgs that made or are making Semi Auto versions of the 44 Magnum.
LAR Grizzly Mark 4 (no longer in production) tough to find and plan on dropping right around $1000 for one.
Israel Arms Desert Eagle 44 mag depends on finsh from Blue to 24k Gold plate.
These are still mfg today and you may be able to get one for $700 and go up up up and away to well over $1000 depending on options.
As you can see, you will need to narrow your choices somewhat.
This list should get you started.
